Cooperative enhancement of channeling of emission from atoms into a nanofiber

TL;DR

This paper demonstrates that a linear array of atoms near a nanofiber can cooperatively enhance the directionality and efficiency of emission into the fiber through guided superradiance, leveraging collective atomic effects.

Contribution

It introduces a method to achieve directional superradiance from atoms near a nanofiber, highlighting cooperative enhancement of emission channeling into guided modes.

Findings

Emission rate into fiber is increased by atomic cooperativity.

Emission becomes highly directional along the fiber axis.

Guided superradiance can be controlled by atomic arrangement.

Abstract

We show the possibility of directional \textit{guided} superradiance from a string of atoms separated by one or several wavelengths in a line parallel to the axis of a nanofiber. We find that the rate and efficiency of channeling of emission from the atoms into the fiber are cooperatively enhanced by the guided modes.
